Abstract

The spatial distribution of multipath fading using miniaturized experimental setup was analyzed. The spatial Fourier transform was carried out for the analysis of the period of fading and we could find out spatial frequency component of fading. Thus the analysis using this method shows the validity of miniaturized experimental setup. The miniaturized experimental setup was made by 5 times reducing of the real size. The simulation was performed at 2 GHz and the measurement was carried out at 10 GHz. Automatic antenna moving system was made for exact measurement of the multipath fading. Both simulated and measured results in miniaturized experimental setup were shown by electric field distribution and spatial frequency density distribution curves.

축소 실험 모형올 이용하여 다중경로 페이딩의 공간분포 특성올 분석한다. 특히 페이딩의 주기 특성 분석을 위 해서 공간 푸리에변환을 통해 페이딩의 공간 주파수 성분을 찾아내는 방법올 이용한다.축소 실험 모형은 실제 환경에 비해 1/5배로 축소되었다. 따라서 실제의 전파모텔 분석에서 사용하는 주파수는 2 GHz이지만, 축소 설험 모형을 이용한 측정에서는 10 GHz를 사용한다. 그리고 페이딩의 정밀한 측정올 위 해서 안테나 자동이송 시스템을 제작하여 실험에 이용하였다. 축소 실험 모형에서의 측정 결과와 이에 대응하는 실제 전파환경에 대한 시융레이션 결과는 전계분포 곡선과 공간 주파수 밀도분포 곡선으로 나타내어 비교하였다.
